Answer:
This system of equations has infinite points of intersection
Step-by-step explanation:
* To know the point of intersection of the system of equations,
you will solve the graphically or algebraically
- Graphically by drawing two lines on the coordinate plane
- Algebraically by substitution method or elimination method
* Lets use the substitution method
∵ y = 4 - x
∵ 2y = 8 - 2x
- Substitute y in the second equation by its value in the
first equation
∴ 2(4 - x) = 8 - 2x ⇒ open the bracket
∴ 8 - 2x = 8 - 2x
* The two sides equal each other, that means we can use any
vales of x, and on the graph they will be the same line for
the two equations
∴ This system of equations has infinite points of intersection
Answer:
The require step to solve the inequality
is
Divide by -4 on each side and flip the sign.
Step-by-step explanation:
What steps should be followed to solve the inequality
Solution:
Divide by -4 on each side and flip the sign.
So the equation becomes
Now minus 4 will get cancel from left and side and in right inside -2 will be there such that (flip the sign)
